It is an entirely other assertion that The Invisible Dragon alleviates suffering, beyond existing.
Let's imagine those who say there is a dragon living in their garage contend that the dragon is a required salve for the harms of living in a hostile world. Though I can not prove (though still approaching with an open mind) the physical existence of a dragon in anyone's garage, I can not argue against the proclaimed effect on those who find their suffering abated. That is, the effect is real if you say it is; the dragon is not.
